FiiO L8 Line Out Cable Stereo Right Angle 3.5mm to 3.5mm

The L8 is packaged with the FiiO E12, and designed to link the music player's headphone socket to the portable amp's line in. The length and flexibility allows the player and amp to be piggy-backed together with elastic bands and put in a pocket. Unfortunately, if your music player is a mobile phone (mine is a Samsung Galaxy W), in anything other than flight mode, the cable does nothing to protect you from EM interference, audible loud enough to interrupt your listening. You will get 'dee-dah-dah-dee-dee-dee-dee-deet' added to your music every time the phone updates itself. Even holding the phone as far away from the amp as the cable length allows, still does not cure the EM problem. I substituted a 30cm length of double-shielded 3mm cable with right-angle adaptors on each end. Although this particular combination of cables does not fit together very snugly, it did cure the EM problem, even when the phone and amp are back to back. The EM shielding problem is therefore attributable to the L8.
